he attachment to avacuuincleaner of a brush mechanism actuatediconjointly with the suction pump of the vacuum ap aratus;

A novel combination of brush mein ers and suction apparatus whereby,foreign matter loosened by the brushmaybecpnveyed into a receptacleforsuch matter attached to said suction apparatus; and .11 1 A new articleof manufacture. comprising a vacuum cleaner apparatus and brush mem berscombined therewith for-increasing the eiiiciency and scope of operationsof the vacuum cleaner, v These, and such other objects as mayhereinafter appear are attained by the novel combination, constructionand arrangement of the several elements which constitute the in--vention, one embodiment of WhlCh 1s 1llustrated' in the accompanyingdrawing, in

which- 1 V J Figure 1 is a schematic arrangement of the device, theparts generally shown in elevation I Figure 2 is a longitudinal section;and

Figure 3 is an end view.

Like reference characters are used to designate similar parts in thedrawin and in the 40 description of the device which ollows. of thedevice is shown as 15.

Only so much required to illustrate its novelty. As the device iscapable of employment upon different types of vacuum cleaners and hasnothing to do with the internal structural arrangement of the vacuumcleanser proper, an illustration of such a cleanser is omitted from theseveral figures hereinabove described.

' Comprising, as it does, an apparatus de- 5 signed for cleansing carbondeposits from Diesel and internal combustion engines, it

must be borne in mind that the structural arrangenient of the embodimentmay be modified. to suit the special work for which the apparatus is tobe used, and therefore, the
